I 18 Claims.

This invention relates to machines for lasting the toe ends of shoes. Theinvention is herein illustrated as embodied in a modification of a' machine constructed generally as disclosed in United States Letters Patent No. granted on July 20, 1943, on an application of mine, but, it is-to be understood that it is not thus limited in its applicability.

The machine shown in the above-mentioned Letters Patent is provided with means for trimming the margin oi -one or more inner layers of the toe-end portion of a multi-ply upper on a last while leaving a margin of the outer layer to be lasted inwardly over'an insole on the last.

The machine also includes a plurality of grippers which grip the margin of theseveral layers of the upper about lthe toe and pull the upper utwardly in directions lengthwise and :widthwise of the last, a nd a toe former whichembraces the upper about the toe and is moved lengthwise of v the last to wipe the upper into conformity to the contour of the toe endof the last while it is held by the grippers preparatory to the upper-trimoperation. Associated with the toe former are wipers which are movable with it heightwise of the last and are also movable to wipe the margin of the outer layer of the upper inwardly over the insole 'after'the upper-trimming operation. Prior to such overwiping movements of the wipers a cement-applying device is moved heightwise of the last into engagement with the toe end'of the'insole andapplies cement thereto for securingthe margin of the upper to the in sole when it is wiped inwardly by the wipersf Movable into operative position with the cementa'pplying device is another device which clamps the margin of the outer layer of the upper outspread on the wipers and serves as a' retarder to assist the wipers in wiping the upper smoothly and tightly over the insole.- In the course of theov'erwipingoperation, moreover, the cementapplying device is ,forced away from the insole by the inward movements of the wipers and serves as an'additional retarder to control the margin of the upper, I

In" accordance with'the' further disclosure of Letters Patent No. 2,337,558; granted on December 28, 1943, on an application of mine, the above-mentionedmachine' was modified in such manner as to cause the grippers again to grip the margin of the upper after,the upper-trimming operation and to apply a pull to the outer layer only of the upper'in order to stretch and shape it more effectively. Prior to this second pull of the. grippers the toe former and the the retarder above referred to as associated with g the cement-applying device in the construction shown in the first-mentioned LettersPatent was omitted.

v The present invention provides a construction whereby the advantages of such a second pull on the outerlayer of the upper after the uppertrimming operation are obtained without the use of thegrippers for that purpose. As in the con-' struction shown in Letters Patent No. 2,337,558, the toe former, and the wipers are withdrawn from the shoes after the upper-trimming operation, the grippers having released the margin of the upper, and are then moved heightwise of the last to cause the toe former to wipe the upper a second time in that direction and to bring the wipers to the proper plane for wiping the margin of the upper inwardly over the insole. For applying the second pull to the outer, layer of the upper there is provided a retarder-which clamps the margin of the outer layer outspread on the wipers before the toe former and the wipers complete their second movement heightwise of the last and cooperates with the wipersduring the completion of that movement to pull the upper. As illustrated, this retarder is associated with the cement-applying device, similarly to the retarder shown in Letters Patent No. 2,324,509, but is differently arranged in relation thereto for the purposes in view. In accordance with one feature of theinvention, moreover,

" novel mechanismis provided for controlling the retarder in such manner as to cause it to move outwardly over the wipers with a wiping action on the margin of the upper to insure that the margin will be smoothly outspread on the wipers.

links which support the retarder and impart the outward wiping movement thereto in response to the movement of the wipers heightwise of the last.

the cement-applying device, which is arranged to serveas an additional retarderashereinabove explained, may be withdrawn from the shoe heightwise thereof to release the upper early in For better results in operating on some kinds of upper materials, both the retarder and the inward wiping movements of the wipers, as further herein illustrated, to provide for less strain on the upper in the overwiping operation.

The above and other features of the invention, including various novel details of construction and combinations of parts, will now be more particularly described with reference to the accompanying drawings and thereafter pointed out in the claims.

In view of the disclosures in the above-mentioned Letters Patent, only such parts of the machine as it is necessary to refer to for an understanding of the invention will be hereinafter particularly described. It will be understood that the machine is a fluid-operated machine in which various mechanisms are operated in predetermined time relation to one another by fluid admitted to cylinder-and-piston devices associated respectively with the difierent mecha nisms, the admission of the fluid and its release from the cylinder-and-piston devices being effected by valves which are controlled by auto matically acting fingers like the fingers 354', 356 shown in Letters Patent No. 2,337,558.

While. any suitable means may be used for positioning the shoe in proper relation to the instrumentalities which operate thereon, the machine herein shown is provided for this purpose, as heretofore, with a plate 2 arranged to be engaged by the bottom face of the toe end of the insole and with a plurality of pins 4 arranged to extend through holes in the insole into holes in the last. Substantially at. the beginning of the power operation of the machine the shoe is clamped against the plate 2 by a toe rest 6 and an instep support 8. To assist in holding the shoe against lengthwise displacement there isalso provided a heel rest 10 (Figs. 1 and 3) movable into .engagement with the heel-end facev of the shoe.

When the operator presents the shoe in the position determined by the plate 2 and the pins 4 he positions the margin of the several layers of the toe-end portion of the upper outspread between the jaws of a toe-end gripper i2 and side grippers M (Fig. 4), and shortly after the beginning of the power operation of the machine these grippers are operated to pull the upper, the toe-end gripper being moved lengthwise of the last and the side grippers widthwise of the last. All three grippers, moreover, receive a comparatively short upward movement. After the pulling of the upper and while it is held under strain by the grippers a substantially U- shaped' flexible toe former I6 is moved upwardly to wipe the toe-end portion of the upper heightwise ofthe last to the edge of the insole and to conform ittothe'contour'ofthe last, and in thisoperation the grippers may be moved somewhat inwardly toward the last-by'the pull of the upper thereon against the resistance of springs (not shown) which control; them; Immediately above the toeformer l6 are wipers III for wiping the margin of the upper inwardly over'the insole, these Wipers being movable upwardly with the toe former to positions where they engage and support the outspread margin of the upper held by the grippers. For the purpose of such upwardmovement of the toe form'erand' the wipers as a unit they are carried by a common support 20 (Fig. 1) mounted. for upward and downward movements on parallel links 22 and 24.

After the upper has thus been wiped heightwise of the last by the toe former, its outspread marginis trimmed to remove therefrom. all but the outer layer of. the upper materials. For thispurpose the machine is provided with uppertrimming mechanism. 26 (Fig. I) mounted on a carrier 28 which is movable downwardly to bring the mechanism. into proper position for operating onthe upper.- The upper-trimming. mechanism includes a pair of side-trimming knives 30 (Figs- 1 and 4) mounted to swing outward laterallyof. the shoe toward the side grippers M from positions over the bottom: of the shoe, and a middle knife 32 movablerectilinearly lengthwise of the shoe in an'outward; direction toward the end gripper l2 tocomplete: the upper-trimming operation after the movements of the side knives. The: middle knife 32" is supported on an arm 34 which: is swung. downwardly' tocarry the knife to the. proper plane for operating on the upper and isv movable bodily to cause the knife to perform the trimmingoperation. Thethree knives, in operating on the; upper, move in a plane parallel tothe top facesof the wipers I8, and in proper time relation to. the movements of the knives:

the: grippers areopened. to release the upper and are then moved farther outwardlyby' their conmovement of the device and the carrier.

the receptacle, and an automatically acting pump.

plunger 42 for delivering the cement. The cement-applying device is carried toa position over the toe end of the'shoe by swinging movement of the carrier 28 about a vertical axis after the carrier has been moved upwardly towithdraw the upper-trimming mechanism 26 from the shoe, and the carrier is then moved downwardly to carry the member 40 of theTcement-applying device into engagement with the insole, as illustrated in Fig. 7, the cement being delivered near the end of the downward movement of the (le vice. The cement-applying device is supported directly on parallel links 44 and 45 mountedrespectively on rods 48 and 50 on the carrier 28,

thus permitting relative upward or downward Spring means not herein shown but disclosed in Letters Patent No. 2,324,509 serves inaddition to gravity to maintain the cement-applying device normally at a predetermined limit of downward movement relatively to the carrier 28 and permits such slight further downward movement of the carrier as occurs after the member 40 of the cement-applyingdevice has engaged the insole.

'After the upper-trimming operation the toe former I6 and the wipers I8 are retracted as a unit from the shoe lengthwise thereof and are moved downwardly, as illustrated in Fig. 6, preparatory to a second upward movement to cause the toe former again to wipe the upper heightwise of the last, the machine herein shown operating in this respect like that disclosed in Letters Patent No. 2,337,558. As distinguished, however, from that prior disclosure, the grippers I2 and I4 remain idle after their first pull on the upper materials and do not apply a second pull to the outer layer of the upper. Instead of using the grippers for this purpose, themachine is provided with a retarder 54 which is moved 7 downwardly with the cement-applying device 36 and thereby assumes a position for clamping the outspread margin of the outer layer of the upper on thetop faces ofthe wipers in. a plane below the edge of the insole when the wipers have been moved upwardly with the toe former far enough to cause such clamping action to occur. Thereafter, during further upward movement of the Wipers with the toe former, the

retarder and the wipers cooperate to apply a pull to the outer layer of the upper.

The retarder 54 is constructed substantially like that disclosed in Letters Patent No. 2,324,509. It comprisesa pair of plates 56 (Fig. 9) curved at their inner edges similarlyfto the edges l of the wipers I8 and provided with downwardly extendside of the bar 66 with thepin 82.

ing' curved flanges 58 for clamping engagement with the upper near the wiping edges of the wip ers.. The plates 58 are provided respectively with upwardly extending tubular portions 60 and 62, one mounted within the other and the inner one mounted ona cylindrical stem 64 on the lower end of a bar 66. The two plates may be adjusted relatively to each other about 'the axis of the stem, and they are held in adjusted positions by a split collar 68 (Fig. '7) which extends around the outer. tubular portion 60 and is contracted by a screw 10, both the tubular portions being split part way downward from their upper ends,

No. 2,324,509, and it is supported by pins 12 and I4 on a; pair of comparatively short parallel links I5 and I8 which are pivotally mounted respectively on pins and 82 in a hollow casing 84. This casing, one wall of which is partly broken away in Fig. 7, is mounted on the two rods 48 and 50 which support the links 44and 46. The casing 84 is provided with vertical slots 86 and 88 through which respectively the rods 48 and 50 extend, and these slots permit the casing to be Vertically adjusted relatively to the carrier 28 to vary the initial position of the retarder 54 heightwise of the shoe relatively to the position of the insole-engaging member 48 of the cement to vary the position of the casing.

A spring 98 connected to an ear 98 on the link It tends in addition to gravity to move the retarder 54 in'a downwarddirection, the limit of its downward movement relatively to the casing 84 being determined .by engagement of one When the retarder 54 is forced upwardly by the wipers in the course of the second up-wiping movement of the toe former I6 the spring 95' is tensioned while holding the retarder yieldingly against the margin of the upper. The force (with which the retarderfthus engages the upper may be varied by adjusting the tension or the spring. For this purpose there is provided an arm I00 connected to the lower end of the spring and fastened to a shaft I02 which is mounted to turn in the casing 84. Also fast on one end of this shaft is an arm I04 provided with a knob I for swinging it to adjust the tension of the spring. The arm I04 is resiliently flexible indirections widthwise of the casing 84 and carries a pin I88 arranged to enter any one of a plurality of holes. H0 in one wall of the casing. By springing the arm I84 in an outward direction the pin may be withdrawn from any of the holes.

to the wipers. The retarder, therefore, has an outward wiping action on the outspread margin of the upper, which afi'ords better insurance that the margin of the upper will be smoothly clamped on the wipers.

By reference to Fig. it will be seen that just after the wipers begin to wipe the margin of the upper inwardly over the insole the upper, still controlled by the retarder 54, is pressed against the inclined face of the insole-engaging member 40 of the cement-applying device 36. By this pressure the member 40 is forced upwardly away from the insole while also acting :as a retarder, as hereinbefore explained. Under some conditions, as when the upperst'ock is of comparative- 1y light weight, it may be desirable to release the margin of the upper from the pressure of both the member lll and the retarder 54 early in the inward movements of the wipers, thus avoiding excessive strain on th upper as its margin is wiped inwardly. This may be done, for example, immediately after the wipers arrive in the positions of Fig. 10, the member 40 and the retarder 54 being lifted as illustrated in Fig. 11 by upward movement or the carrier 28. This carrier is moved downwardly to carry the upper-trimming mechanism 26, and thereafter the cementapplying device 36, toward the shoe by fluid admitted into the upper end of a cylinder I I2 (Fig. l), the fluid acting on a piston I14 to which the carrier 28 is secured; and upward movement of the carrier is effected at the required times by a spring H6 acting on the piston H4 when fluid is released from the cylinder H2. To cause the carrier to be moved upward precisely at the time required to release the margin of the upper as above described, it is. only necessary properly to adjust the automatic means whereby fluid is released from the cylinder H2.

The manner of operation of the machine, in so far as it is of interest for an understanding of the present invention, will now be briefly summarized with reference particularly to the chart.

(Fig. 13) which shows the preferable timing of the various operations. On this chart, as on a similar chart in Letters Patent No. 2,337,558, the double lines indicate the times when the operating fluid'is effective to operate the parts or 'to perform the operations designated, or to maintain the parts in positions to which they have been moved, and the single lines indicate the times when the pressure of the fluid thus acting is relieved. A comparison of the present chart with that in the above-mentioned Letters Patent will show, as far as the timing of the valves is concerned, the changes that have been made in the cycle of operations for purposes of this invention, these changes resulting from omission of some of the previously mentioned valve-controlling fingers and from [adjustment or rearrangement of others of the fingers.

When the operator presents the shoe to the machine in the position determined by the plate 7. and the pins 4 he positions the margin of the several layers of the toe-end portion of the upper outsp-read between the jaws of the grippers l2 and M, and prior to the starting of the cycle of operations of the machine the grippers are closed, as heretofore, on the several layers. Immediately after the starting of the cycle the toe rest 6, the instep support 8 and the heelrest it? are moved into their operative positions, and shortly thereafter the grippers are operated to pull the toe end of the upper lengthwise and laterally, as illustrated in Figs. 2 and 4. While the grippers are holding the upper under tension the carrier 28 which supports the upper-trimming mechanism 26 and the cement-applying device 36 is moved downwardly to carry the upper-trimming mechanism into position to operate on the shoe, and upward movement is imparted to the support 20 to raise the toe former l6 and the wipers l8 and thus to cause the toe former to wipe the toe end of the upper toward the edge of the insole into conformity to the contour of the toe end of the last, as illustrated in Fig. 3. The next operation performed is the trimming of the upper by the movements of the trimming .knives 30 and 32, the action of the middle knife 32 on the upper being illustrated in Fig. 5. In time relation to the movements of the trimming knives the grippers are opened to release the upper and are retracted from the paths of movement of the knives by the springs which control them, the grippers being thereafter heldin retracted positions until near the end of the cycle by maintaining the fluid pressure in the devices whereby they are operated. It will be understood that by the action of the trimming knives, moving in a plane parallel to the wipers l8 over the marginal portion of the upper materials supported on the top faces of the wipers, the margin of all but the outer layer of the toe-end portion of the upper is trimmed ofi, leaving the margin of the outer layer to be lasted thereafter inwardly over the insole next to the insole. While the drawings, for convenience, show only a single layer of upper materials in addition to the outer layer, it will be understood that the toe-end portion of the upper will usually comprise at least three layers of materials. After the trimming operation the carrier 28 is raised to withdraw the trimming mechanism from the vicinity of the shoe and the trimming knives are returned to their starting positions on the carrier.

Shortly after the trimming of the upper the Wipers and the toe former are retracted from the shoe lengthwise thereof and are released for downward movement by gravity, as illustratedin Fig. 6. Thereafter, the carrier 28 is swung to carry the cement-applying device 36 to a position over the toe end of the shoe and is moved downwardly to carry this device into engagement with the toe end of the insole and to apply cement to the insole, as shown in Fig. 7. Movable downwardly with the cement-applying device is the retarder 54 the upper-engaging flanges 58 of which deflect the outturned margin of the outer layer of the upper downwardly beyond the edge of the insole, as also illustrated in Fig. 7. Shortly thereafter the wip'ers and the toe former are moved reversely lengthwise of the shoe and are raised to cause the toe former again to conform the toe end of the upper to the contour of the last. Again the wipers in their upward movement opposite the toe-end face of the last with the toe former arrive in positions to clamp the outturned margin of the outer layer of the upper against the retarder 54 in a plane below the edge of the insole, the wipers and the retarder cooperate during further upward movement of the wipers to apply a pull to the outer layer only of the upper materials, as illustrated progressively by Figs. 8 and 10; As upward movement is imparted to the retarder by the wipers against the resistance of the spring 96, the links 76 and 18 which support the retarder are swung toward horizontal positions and thereby impart to the retarder an outward movement lengthwise of the shoe over the wipers. The retarder by its outward Wiping action on the margin of the upper thus insures that the margin will be clamped smoothly on the wipers. After the upward move over .the insole.

ment of the toe former and theiwipers, movements are imparted to the wipers to wipe the marginof the outer layer of the upper inwardly Just after the wipersbegin to wipe the margin of the upper inwardly over the insole the upper, which is stillcontrolled by the retarder G, is pressed by the wipers against the inclined face of the insole-engaging member 40 0f the cement-applying device 36, and in response vto this pressure the .member 40 begins to move upwardly away from the insole while acting as an additional retarder, as illustrated in Fig 10. Immediately thereafter the carrier 28 is moved upwardly'to cause the member 40 and the retarder 54 to release the margin of the upper (Fig.

11), thus avoiding excessive strain onthe upper as disclosed in Letters Patent No. 2,337,558.

In a toe-lasting machine, wipers for wiping the margin of the" toe end of an upper inwardly over an insoleon a last, a retarder for clamping the margin of the upper outspread on said wipers, a support for said retarder, said support and the wipers being relatively movable heightwise of the last while the retarder is in upper-clamping position, and means on said support for controlling vthe retarder, said controlling means being mounted to swing in response to such relative movement of the support and the wipers and thereby to move the retard'er outwardly over the wipers while maintaining it in parallel relation to the wipers.

14. In a toe-lasting machine, wipers for wiping the margin of the toe end of an upper inwardly over an insole on a last, a retarder for clamping the margin of the upper outspread on said wipers, a support for said retarder, said support and. the wipers being relatively movable heightwise of the last while the retarder is in upper-clamping position, and parallel links on' said support arranged to control the retarder and to move it outwardly over the Wipers inresponse to such relative movement of the support and the Wipers.

15. In a.v toe-lasting machine, wipers for wiping the margin of the toe end of an upper inwardly over an insole on a last, said wipers being movable heightwise of the last before thus wiping the margin of the upper inwardly, a retarder arranged to clamp the margin of the upper outspread on the wipers and to cooperate withv them toapply a pull to the upper as the wipers are moved heightwise of the last, and parallel links arranged to support said retarder, said links being inclined iii retarder an outward wiping movement over the wipers in response to the movement of the wipers heightwise of the last.

16. In a toe-lasting machine, wipers movable to wipe the margin of the toe end of an upper in-- wardly over an insole on a last, a retarder arranged to engage the toe end of the insole in the path of the wipers and to clamp the margin 01 the upper againstthe Wipers as they begin to wipe it inwardly over the: insole, and a carrier support.-

from between it and the wipers by the movement ing said retarder and movable t withdraw it from contact with the upper before the margin of the upper is withdrawn from between it and the wipers by movement of the Wipers.
